A portable field rapid detection device for harmful substances in wine

Abstract

The invention discloses a portable device for on-site quick detection of harmful substances in wine. The device comprises a quantitative sample extraction module, a signal processing circuit module, a single-chip microcomputer signal acquisition system, a power source module, a touch screen module and an online storage module. The quantitative sample extraction module is used for quantitatively extracting a wine sample, methyl alcohol and volatile acid in the wine sample are sensed through a sensor, content information is converted into an electric signal to be transmitted into the signal processing circuit module to be amplified, denoised and filtered, the electric signal is transmitted into the single-chip microcomputer signal acquisition system after being converted by an A / D conversion circuit and then is processed by the single-chip microcomputer signal acquisition system and displayed on a touch screen of the touch screen module, and a measurement result is transmitted into the online storage module to be stored or guided out online. The portable device is portable, high in response speed, high in measurement precision, simple in structure, small in size, low in weight, waterproof, resistant to explosion and convenient to maintain, and especially a liquid suction head can be replaced, so that on-site detection speed is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of rapid detection, in particular to a portable on-site rapid detection device for harmful substances in wine. Background technique [0002] Wine is made from grapes through fermentation. Wine contains many nutrients, such as sugars, alcohols, acids, inorganic salts, amino acids and various vitamins. It not only tastes sweet and mellow, but also has rich nutrition, and has the functions of lowering bad cholesterol, promoting digestion, strengthening body, and beautifying, so it is loved by the majority of people. In recent years, with the continuous development of social economy and the continuous improvement of people's living standards, many families choose to make wine by themselves. Wine brewing needs to go through links such as material selection, cleaning, drying, crushing, fermentation, and clarification. Since wine is easily contaminated by bacteria during the brewing process, each link has very st...

Problems solved by technology

At present, although there are portable methanol and volatile acid measuring instruments on the market, these instruments can only measure a single harmful substance, and have disadvantages such as not being portable, not fast, and relatively expensive. Therefore, it is necessary to develop a method for detecting wine Portable device with medium methanol and volatile acid content, serving for families and individuals
